The headers are XSPower 1 7/8" catted fully 3" through the mufflers. They're basically a nice quality, ARH knockoff. I have a vette, so sorry American vendors, but I'm not spending a ludicrous $1600 for catted headers (not like they care lol)
I'm sure it'll be a big difference. It's going to be interesting to see how close, mph wise, I get to my old max effort 460 rwhp h/c/i cathedral setup with this wonky setup. If I can trap 122-123, I'd say they're equal considering this forged motor is lower compression. I trapped 124.6 in the old setup, but it was in arctic air. It was normally a 123.5ish trap car.

LOL I was one of them! I like trying new stuff though and BSP had a very attractive price. I am sure the MAST 62cc ones work even better. Would love to see someone try those on a 347.

got a long ways to go but mine are going on my sbe shortblock, already emailed ed on a custom cam so well see how it goes within the next couple months. current setup is cam only 228/234 588/598 custom cam, edelbrock stepped longtubes, fast 102 setup, m6 blah blah blah. pretty excited, but taking it slow as we have a baby on the way.

Phones acting funky, but I haven't ordered the valves yet but I'm set on them just like I was set on running these. so far I have 2250 in the bare heads and ls3 intake. I already have the ls3 rail on my 102 setup along with the fast 92 tb. all I need to find is some used injectors but I have a lead on some locally for 100 bucks. I have 1600 in my fast setup alone, should a done this sooner lolz

Only 2300 for the masts? Damn, when I was looking at the small bores all I could find was a $3300 price, which is why I went with the budget BSPs.
If I knew about these for $2300 I would have picked them up.
